Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / February 2005emergency tyre repair
I'm in france with survival-only french so was not able to fully understand the implications of a quick burst tyre repair I've just had carried out to get me back to base. This particular garage was unable to find a tool to fit these particular wheel bolts and I couldn't find one in my car kit either so he squirted a can of gunk into the tyre and when that didn't work used an odd looking flexible stick of something which was brutally forced into the puncture and seems to be working. (as will be evident, I haven't a lot of experience with this sort of thing!). How long is a fix like this usually good for before I can next get to a properly equipped garage and replace the wheel? The pressure seemed to be fine after 20 miles or so - what are the chances of another 20miles? Is time itself a factor whether driving on it or not? what have others' experiences been? thanks Both usually work, sometimes for the rest of the life of the tire. One is a glue goop that will stop a lot of flats and holds for years from my experience. The 'plug' he used was more for bias ply tires and can leak because of the extra flex in a radial to give a slow leak or it can hold until there is no more tread left to hold it in place. They usually combine a plug and a patch on radials for a really good flat fix. I carry 'both' of the above fixes in my trail box for my CJ7 and in the misc.. parts box that stays in my wife's Cherokee or any current vehicle. They have been used with success more than once.

That might throw off the balance, and any tire warranty is kaput after using that stuff. > The 'plug' he used was more for bias ply tires and can leak because of > the extra flex in a radial to give a slow leak or it can hold until > there is no more tread left to hold it in place. > > They usually combine a plug and a patch on radials for a really good > flat fix. The current industry standard is a "mushroom" shaped plug/patch. The plug portion comes in variable diameters, and is permanently attached to the patch. > I carry 'both' of the above fixes in my trail box for my CJ7 and in the > misc.. parts box that stays in my wife's Cherokee or any current > vehicle. They have been used with success more than once. Those are generally considered to be temporary fixes. The tire really should be dismounted, inspected on the inside, and balanced. But if you're in the middle of France with little ability to communicate, then it might be an option until you can find someone who speaks English. > > Both usually work, sometimes for the rest of the life of the tire. > > Sometimes, but I'm wary of the plug loosening and shooting out. I worked in tire shops for years and 'never' saw a plug that fell out or the empty hole left. The issue is leaking through the plug on a radial because of the flex. Bias ply tires didn't flex the same so the plug didn't get worked hard to start it leaking until the tread got really thin. They changed to solid rubber strips for radial plugs to help avoid the 'leak through the middle' syndrome. > > One is a glue goop that will stop a lot of flats and holds for years > > from my experience. > > That might throw off the balance, and any tire warranty is kaput after > using that stuff. Not so at all. The liquid spreads evenly because of rotational force and it does nothing to any warranty. I have used the stuff several times and then changed the tire under road hazard warranty. > > The 'plug' he used was more for bias ply tires and can leak because of > > the extra flex in a radial to give a slow leak or it can hold until [quoted text clipped - 6 lines] > The plug portion comes in variable diameters, and is permanently > attached to the patch. Exactly, that is the best. > > I carry 'both' of the above fixes in my trail box for my CJ7 and in the > > misc.. parts box that stays in my wife's Cherokee or any current [quoted text clipped - 5 lines] > ability to communicate, then it might be an option until you > can find someone who speaks English. Agreed, meanwhile he should just watch the air level for a while in case of a slow leak.

Lots of the cheezy self-repair kits I've seen use rubber strips that look similar to red/black licorice, and only come in one size. I thought that one of the important things is to get the proper size for the hole. And the size of the hole often can't be assessed without seeing the inside of the tire. >>>One is a glue goop that will stop a lot of flats and holds for years >>>from my experience.

I just got a set of Pirelli P Zero Nero M+S tires. Here's what's not covered under Pirelli's US warranty: <http://www.us.pirelli.com/en_US/tyres/car_suv/utility_services/warranty/wnotcov.jhtml> --quote-- What Is Not Covered By The Warranty? • Tires improperly repaired or with repairs not conforming to Rubber Manufacturers Association standards, or with section repairs, or with self-vulcanizing plug only. • Tires injected with liquid balancer or sealant or in which anything other than air has been used as the support medium. --unquote-- > >>>Both usually work, sometimes for the rest of the life of the tire. > >> [quoted text clipped - 40 lines] > > --unquote-- Ahh, you are right on that, forgot about the old 'exploding' spray sealer and I don't blame them for not covering a plug, though I wonder about the string plugs vs the rubber self vulcanizing strips now that they specifically ban only one type of plug??? The new type of spray sealers I see on our Canadian shelves don't use the bad chemicals as accelerants anymore, they now say 'safe' and use air I believe. The downside is they now freeze so you have to thaw them before using. I don't have the Cherokee home right now to see exactly what they use in the one I currently have. The last can got used to get us to the garage for a proper flat fix. They still did the flat fix under warranty because it was a repeat of a rim leak, not a puncture as it turned out. There are a bunch of new flat fix systems out with just the sealer in a can and an air pump to pump through the can so it is just air inside. One uses a sealer by Dunlop. http://www.canadiantire.ca/assortments/product_detail.jsp?FOLDER%3C%3Efolder_id= 1408474396669459&ASSORTMENT%3C%3East_id=1408474396670271&bmUID=1108575977494&PRO DUCT%3C%3Eprd_id=845524443276876&assortment=primary&fromSearch=true I don't know if that link will work but go here and type in tire repair in the search window. http://www.canadiantire.ca Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's I have used these and driven two years with no problem in a 1975 chevy van, 1989 ford bronco and others. great fix and reliable. old john > I'm in france with survival-only french so was not able to fully understand the > implications of a quick burst tyre repair I've just had carried out to get me [quoted text clipped - 11 lines] > what have others' experiences been? > thanks |
